MACHINE FOR PlLlNG TEXTILE FABRICS.

SPECIFICATION forming part of Letters Patent No. 396,720, dated January22, 1889.

- Application filed June 13, 1888. Serial No. 276,976. (No model.)

To all whom it may concern:

Be itknown that I, OTTO lVOLESOHN, of the city, county, and State of NewYork, have in vented certain new and useful Improvements in Machines forPiling 'lextile Fabrics, of which the following is a specification.

This invention relates to machines for piling textile fabrics intolayers for cutting into different shapes for making garments.

The object of. the invention is to provide a machine of this characterwhich may be op erated with facility.

In the accompanying drawings, Figure 1 represents a verticallongitudinal section of my improved machine for piling textile fabrics,taken on line 00 :0, Figs. 2 and 3. Fig. 2 is a plan of one end of thesame, showing the gages in horizontal section; and Fig. 8 is a verticaltransverse section on line y y, Fig. 1, showing an end elevation of thetraversingcarriage and fabric-holding clamp.

Similar letters of reference indicate correspondin g parts.

Referring to the drawings, A represents a cutting table orbench ofsuitablelength. At one end of the cutting-table is arranged a fixedstand, 13, the upright standards '5 of which support in recesses b anysuitable number of rolled or folded pieces of. fabric, according to thenumber of layers that are to be doubled on the cutting-table. The standards B B are connected by transversi-i tension-rods and (1, over whichthe different layers of fabric are conducted. At the base of thestandards B B isarranged a transverse stretching bar or roller, D, overwhich all the layers of fabric are stretched.

On the tensionrods C are arranged laterally-adjustable gage-plates E,which are adjusted to the width of the fabrics and which serve to guidethem and produce the regular overlapping of the same. The stretching-barD is arranged close to the cuttingable, as shown in. Fig. 1. The ends ofthe fabrics are conducted from the stretehing-lmr I) to a stretehingbar,g, and clamping device f f of a traversirig-carriage, F.

The traversing-carriage F is constructed of upright standards F, whichextend above and below the cutting-table A, and which are provided withways a a, for being guided along the cutting-table A. The table Aisprovided with longitudinal racks (Z at the underside of the same, whichracks are engaged by pinions (1', the shaft of which turnsin bearings ofthe standards F below the table A.

Gear-wh eels (Z on a second shaft mesh with the pinions d, the shaftbeing provided with a hand-crank, d, by turning which the carriage F ismoved by means of the intermeshing pinions and racks in one or theopposite direction over the cutting-table A. The clamping device f f isarranged at the upper part of the carriage F, and is composed of a fixedlongitudinally-serrated j aw,f, and of a 1novable upper jaw, f, whichlatter is guided in recesses of the standards F and supported bycushioning-springsf The jaws f f may be provided, in addition to thelongitudinal teeth or serrations, with one or more pointed pins,

f which pierce the fabrics and hold them firmly in connection with thelongitudinal ribs or serrations on the faces of the jaws ff. After thefabrics have been placed in position on the lower jaw, f, the upper jaw,f, is pressm'l. down on the same by an eccentriclever, F which ispivoted to a lug, f, of the top piece or yoke, F, which connects thestandards 1 said okebein )rovided \\'ith a slot for the eccentriecam 1 Atransv rse plate, A, is attached below th on .ble A to the lowerguideways, (1, ar nt upward, so as to form contact wil e under side ofthe table and steady th i I the carriage in its motion over the table A.

The transverse stretching-bar g of the carriage F is located close tothe cutting-table and serves for guiding the fabrics onto the clam p ffan d for stretchin them tightly over the cutting-table A in connectionwith the stretching-bar ID of the stand B.

)Ily machine for piling textile fabrics is operated as follows: Therolled or folded pieces of fabric are placed in the recesses of thestandards B B and then passed over the different tension-rods in such amanner that a certain friction is exerted by the same on the fabrics,and the latter are slowly and uniformly unwound from their cores, whichare provided with pivots, so that the pieces of fabric can bodily tn rnon their axes. \Vhen the different fabrics to be piled havcbeen passed.over the tension-rods C Q, the vertical gage-plates E are adjusted tothe width of the same and the fabrics then passed below the fixedstretch ing-bar D at the base of the t'almic-supporting standards l3,and from the same to and below the stretching-bar g of thetraversingcarriage F, which latter has been moved up close to thestretching-bar .l). The ends of the fabrics are then tightly clamped bythe jaws ff, which accomplished by the eccentric F Thetravcrsing-carriagc F is next slowly moved over the putting-table A byturning the hand-crank d and [)l'OtlllOllLQ' the internleshing ol thegear-wheels 1F,pinions It, and racks (1 until the carriage arrives atthe opposite end of the cutting-1able. The layers of fabric are therebystretched tightly on the cutting-table, one above the other, in piledupstate, and are held in this position for the action of the cutter. Whenthe length of the fabric between the stretching-bars D and g is cut up,the travei-singcarriage 1 is moved back to the stretching-bar l), andthe ends of the fabric clamped again to the jaws of the clamp, afterwhich the carriage is again moved forward until it arrives at theopposite end of the table, piling thereby a new length of fabrics on thecutting-table ready for cutting, and so on.

The advantage of my improved machine for piling textile fabrics is thatthe piling can be accomplished in a quick, uniform, and reliable manner,ready for cutting.

Havin thus described my invention I claim as new and desire to secure byLetters Patent The combination of a cutting-table, a supporting-staml atone end for the fabrics, and a trave]'sing-carriage provided with astretcher bar, a fixed clamping jaw, a verticallyinovable clan'ipingjaw,springs for forcing said jaws apart, and an eccentric for pressing themtogether.

In testimony that I claim the foregoing as my invention I have signed myname in presence of two subscribing witnesses.
